[HP99] 159 -- Properties of the first Supersoft X-ray Source with a Helium star donor

Hélène Szegedi, Philip A. Charles, David A. H. Buckley +3

[HP99] 159 is remarkable as the first supersoft X-ray source (SSS) identified with an evolved helium star donor. With a likely orbital period of 1.164 d or 2.327 d, the origin of t…

Exploring Hard X-ray Properties of -ray Emitting Narrow Line Seyfert-I Galaxies through NuSTAR Observations

Suvas Chandra Chaudhary, Raj Prince, Brian van Soelen +1

We studied the six gamma-ray-detected Narrow Line Seyfert 1 (NLSy1) galaxies using the hard X-ray observations from Nuclear Spectroscopic Telescope Array (NuSTAR) and optical g- \&…

Insights into the Long-term behavior of the optical polarization from the blazar 1ES 1959+650

K K Singh, A Singh, A Tolamatti +2

A high degree of linear polarization measured in the optical emission is an important observational feature of blazars. It provides strong evidence of the presence of relativistic…

Millinovae: A New Class of Transient Supersoft X-ray Sources without a Classical Nova Eruption

Przemek Mróz, Krzysztof Król, Hélène Szegedi +18

Some accreting binary systems containing a white dwarf (such as classical novae or persistent supersoft sources) are seen to emit low-energy X-rays with temperatures of ~10^6 K and…

Joint H.E.S.S. and Fermi-LAT analysis of the region around PSR J1813-1749

T. Wach, A. M. W. Mitchell, V. Joshi +1

HESS J1813-178 is one of the brightest sources detected during the first HESS Galactic Plane survey. The compact source, also detected by MAGIC, is believed to be a pulsar wind neb…
